Abstract

A system provides real-time previsualization of effects to be added to high definition (HD) video data and real-time rendering of the HD video data including the added effects. The computer based system for editing high definition television (HDTV) resolution video includes a high definition video system connected to a standard definition video system and a high definition storage system. A resizer reformats the high definition video data to standard definition resolution for real-time processing and previsualization.

Claims

1. A nonlinear editing system for editing a program from one or more high definition sources, comprising:

a random access computer readable medium for storing a plurality of sequences of digital images corresponding to the one or more sources, wherein each of the plurality of sequences is stored in a data file and wherein each image is a high definition image;

an editing interface that allows a user to specify a representation of the program using a sequence of segments of said plurality of sequences of digital images stored on the random access computer readable medium;

a resizer having an input connected to receive high definition images from the random access computer readable medium and having an output for providing standard definition images obtained by resizing the high definition images by reducing a number of lines and by changing aspect ratio;

a standard definition display connected to the output of the resizer that displays the standard definition images output by the resizer;

a high definition display having an input connected to receive high definition images from the random access computer readable medium that displays the high definition images; and

a playback module that receives the representation of the program and causes images of the program to be displayed on the standard definition display and the high definition display at substantially the same time and in real time.

2. A nonlinear editing system for editing a program from one or more high definition sources, comprising:

a random access computer readable medium for storing a plurality of sequences of digital images corresponding to the one or more sources, wherein each of the plurality of sequences is stored in a data file and wherein each image is a high definition image;

an editing interface that allows a user to specify a representation of the program using a sequence of segments of said plurality of sequences of digital images stored on the random access computer readable medium, wherein each segment is defined by a reference to one of the plurality of sequences of digital images and a range in the sequence of digital images;

a resizer having an input connected to receive high definition images from the random access computer readable medium and having an output for providing standard definition images obtained by resizing the high definition images by reducing a number of lines and by changing aspect ratio;

a standard definition display connected to the output of the resizer that displays the standard definition images output by the resizer;

a high definition display having an input connected to receive high definition images from the random access computer readable medium that displays the high definition images; and

a playback module that receives the representation of the program and causes images of the program to be displayed in synchronization and in real time on the standard definition display and the high definition display.
